The susceptibility of radar search antennas to radio-frequency interference (RFI) is determined to a great extent by the minor lobe structure. The use of detailed, three-dimensional patterns to predict RFI is not practical because the fine structure of the antenna pattern changes with frequency, range in the Fresnel zone, and site effects. Statistical gain studies have shown that the characteristi...

The majority of the work on the measurement of spurious responses in receivers done up to now is based upon the measurement of the sensitivity of all spurious responses for each of a few (usually three) tuned frequencies within the tuning range of any one receiver or major radio frequency head. These responses have been identified as the products of the nonlinear mixing of the incoming and local o...

The shielding effectiveness of conductive glass at low and intermediate frequencies (100 kc to 1,000 Mc) was investigated. A mathematical model was used to describe the absorption and reflection. This model is based on a film applied to the glass substrate which represents a barrier with finite thickness and relative conductivity. Experimental data agreed well with theoretical calculations. Coated...

Although several proprietory finishes have been available for aluminum and magnesium protection from corrosion, the electrical properties at radio frequencies have never been sufficiently defined. In order to evaluate the relative merits of such finishes for aluminum and magnesium, a test program was established. Fixtures were designed to measure bonding impedance from dc to RF, and to evaluate sh...

Transmitter power is a fundamental parameter with respect to the performance of electromagnetic equipment, determining the strength of signals that may be either desired or undesired at particular receivers. The rational assignment of power output to transmitters for which this is a controllable variable is one method of enhancing compatibility in congested electromagnetic environments. It is show...
